DC WELDING:
- We gain a smoother welding because of constant and linear direction of current.
- The arc will be more stable and easier to handle.
- DC welder can use both AC and DC welding rods.
- The arc is not stable here and needs to be stuck again because of the fluctuating nature of AC.
- It is not as smooch as DC welding.
- These welders cost less when compared to DC welders.

What is the difference between ac arc and dc arc welding?
Both are shielded metal welders but differ in the electricity they use. Ac welders can weld heavier metal while dc welders are better for thinner metals. Ac welders can weld magnetized metals. Dc welders can not. The arc in an ac welder is harder to control because of the pulsating current. Dc welders are more expensive. Some welding machines offer both options.
Which type of welding is preffered ac arc welding or dc arc welding and why?
Both currents have their ups and downs but both are used in the maufacturing industry, in reality it depends on your base metal and electrode.
What are the three types of machines used in manual metal arc welding?
I am not sure your question is clear enough but here I go... Stick Arc Welding (AC or DC), MIG (Metal Inert Gas) and TIG (Tunsten Inter Gas). All three of these are the basic metal welding machines.
What is the difference between an arc welder and a stick welder?
Stick welding is also more difficult to learn and use, particularly the ability to strike and maintain an arc. Arc welders are available in AC, DC or AC/DC, with AC being the most economical. It's used for welding thicker metals of 1/16 inch or greater.
Why ac is more popular then dc for metal arc welding?
A: Very simply efficiency. DC requires rectification from AC. Which will waste this process as non working heat
I have a chicago electric 180 acdc arc welder can i use the same welding rod for either ac or dc welding?
Some electrodes (welding rods) can be used AC or DC. Some are strictly DC. You may find that most electrodes run smoother on DC. Most industries purchase machines with DC capability.
What is the difference in welding rods for ac welders and dc welders?
The difference in the ac/ dc , or polarity of welding rods is in the makeup of the flux coating , or the alloy of the metal, and in the case of SMAW ( Shielded metal arc welding ) rods , which have a flux coating, are usually marked on the base of the rod.
Why is it that ac arc welding is more common than DC arc welding?
I am not sure that it is more common. The large welding rigs that are mounted on trucks mostly use DC, but they can be set for AC. If the question is based on a survey of the cheap welders at a retail outlet, the answer would be that AC welders are simpler to make, since only a transformer is required to change the voltage. A DC welder needs to convert the power from AC to DC, which is more complicated and therefore more expensive. Cheap welders may be easier to sell to a beginner, therefore more of the welders would be AC.
What is MMA welding?
MMA stands for manual Metal Arc welding. In short "arc welding" and can be used in either AC or DC mode. Usually incorperated with Mig, Tig and plasma cutters for arc welding machines as an optional extra. submitted by Ken.Benson - Clarke. sales@edacomputers.co.uk from saffon walden, essex, uk.
What would happen if you use 6010 welding rod on an AC welding machine?
6010 is intended for DC welding. It has no additives in the covering to keep the arc going each time the AC voltage reverses, so it is very hard to keep the arc struck. The result is usually poor quality welds. The solution is to switch to a rod designed for AC, such as 6013.

What type of welding can you do with an ac welding machine?
You can do Shielded Metal Arc Welding (stick) with an appropriate electrode. If the machine has a high frequency arc stabilizer then you can also TIG (tungsten inert gas) weld aluminum. Wire feed processes require a DC machine
